FOR THE ATTENTION OF OPERATORS
1. Before starting work thoroughly study the present operation manual and strictly follow
all operation and maintenance directions.
2. Be sure to run the tractor in for thirty hours. Put load up to 80% of rated power before
the first maintenance M-1 (125 hours).
3. Your tractor is equipped with range-type gear box. It means ranges are shifted by
means of toothed-type coupling and gears within each range – by synchronizers.
To shift the range:
— Press out the clutch pedal and wait until full tractor stop;
— Using range shifting lever smoothly and without jerks engage the required range;
— Smoothly release the clutch pedal.
To put in gear:
— Press out the clutch pedal;
— Smoothly, without sharp jerks move gear shifting lever and hold it pressed until gear is
fully put in;
— Smoothly release the clutch pedal.
Put in gears within the range while running only during transport operation on hard surface
and dirt roads. During the off-road (ploughed field, peat field, sand soil) tractor travel
gear shifting while running IS NOT ALLOWED due to sharp stop of the machine. In this
case use earlier selected gear to travel across these legs. Failure to observe these
operation directions leads to fast wear of gears’ splines and toothed-type couplings, as
well as damage of synchronizers.
ATTENTION! If, with clutch pedal pressed out, ranges and gears are shifted with grinding
sound, promptly address the dealer’s center to correct malfunction.
4. Follow directions for switching PTO. With PTO control lever engaged, smoothly, with
2…4 s delay in the middle of travel from the neutral to PTO switching to avoid damage
of shaft, reduction gears and PTO driving end.
5. Make adjustment of wheel and parking brakes only on horizontal terrain with diesel shut
down and wedges placed at the front and back sides of rear wheels to exclude
accidental movement of the tractor.
6. Do not operate the tractor without storage batteries connected to the electrical
equipment system and “ground” switch being off with the running engine.

ATTENTION! Prolonged and reliable tractor operation is possible only if
proper operation and timely maintenance are observed
ATTENTION! Before putting new tractor into operation study the present
operation manual and strictly follow recommendations thereof, to avoid accidents,
injures or mutilations.
Note: Reference in the present manual text made to “left-side” or “right-side”
are made from the view of the observer standing behind the running tractor.
Note: Due to constant tractor update and improvement of working conditions,
changes, not indicated in the present edition, may be introduced to the tractor
design.
Re-equipment and alteration of tractor design without approval of the
manufacturer are forbidden.

Section B Safety requirements
Strict observance of precautionary
measures and abidance by tractor
control and maintenance directions
guarantee complete safety of its
operation.
General directions
Carefully study operator’s manual
before using the tractor. Insufficient
knowledge of tractor operation and
maintenance may be the cause of
accidents.
1. The tractor can be operated only
by trained and qualified
specialists briefed on safety
engineering and fire safety.
2. If tractor is provided with safety belt,
use it during operation. If tractor is
not equipped with safety belt,
address your dealer.
3. Do not place a passenger in the
cabin, unless additional seat and
railing are provided. There is no
other safe place for a passenger in
the cabin!
4. Keep all warning plates tidy.
5. If plates are damaged or lost,
replace them with new ones.
6. Before starting work carefully
examine the tractor, trailing
machine, mounted implement and
hitch. Start the work only being
sure they are fully operational.
Trailing agricultural machinery and
transport trailers must be provided
with rigid hitches, excluding their
sway and run-over during
transportation.
Precautionary measures during
tractor operation
Attention! Do not start the diesel
being out of operator’s working seat.
Stay always inside the cabin during
diesel start up and controls
manipulation.
7. Before starting the diesel, parking
brake should be engaged, lever of
power take-off shaft (PTO) in the
position “off”, levers of range and
GB gears shifting – in the position
“neutral”. Switch of GB pump drive
should be in position driven from
“diesel”.
8. Do not start the diesel up and do
not use control levers being out of
operator’s working place.
9. Before starting movement warn
people around and those working
on trailing machines with a horn.
10. Do not leave the moving tractor.
11. Before leaving the cabin disengage
PTO, engage parking brake and
pull out starter switching key.
12. Do not operate the tractor inside
closed rooms not properly
ventilated. Exhaust gases may
be the cause of death!
13. When malfunction appears
immediately stop the tractor and
correct the trouble.

13.1. If diesel or steering wheel fail
during operation, immediately stop
the tractor. Remember that with
diesel shut down much greater effort
has to be applied to the steering
wheel.
14. Do not work under lifted agricultural
implements. During prolonged
breaks do not leave mounted
implement in lifted position.
15. If the front part of the tractor drives
off the ground when mounting heavy
machines and implements, put front
load.
16. When operating with frontal loader
fill rear tires with liquid ballast.
17. Before lifting or lowering a mounting
agricultural implement, as well as
when turning, make sure in advance
that there is no danger of brushing
against somebody, or hit against an
obstacle.
18. During transport travel with mounted
machines or implements always use
mechanism for fixing the mounting in
the lifted position (for HMS without
hydraulic lift).
19. The gimbal gear for transferring
rotation from tractor PTO to
assembly tools should be protected.
20.Make sure any additional equipment
or auxiliary devices are properly
installed, and also that they are
intended to be ganged up with your
tractor.
Remember, that if not properly
operated, your tractor may be
perilous both for you and other
persons. Do not use equipment
not intended for use on yoyr
tractor.
21. To avoid overturning take care
when running the tractor. Choose
safe speed in accordance with road
conditions, in particular when
travelling on cross-country terrain,
across ditches, slopes and at sharp
turns.
22. When operating on slopes expand
tractor wheel span to maximum.
23. Do not turn sharp under full load
and at high travelling speed.
24. When using tractor for transport
purposes:
•Increase tractor wheel span up to
1600 mm (64’’);
•Interlock braking pedals, check
and adjust brakes for synchronous
action, if necessaryс;
•Check functioning of parking brake;
•Check state of light and sound
alarms;
•Transport trailers should be
provided with rigid hitch and
additionally coupled by means
safety chain or steel rope;
•Never move down the hill with gear
disengaged (coasting). Move at one
and the same gear both uphill and
downhill;
•Do not operate the trailer without
stand-alone brakes, if its mass
exceeds by half total actual
tractor mass. The faster you
move and the larger the mass
being towed, the larger safe
distance should be;
•Disengage FDA to avoid
excessive wear of driving parts
and tires .
